ATTORNEY Patented June 22, 1943 UNITED STATES PATENT OFFICE MEANS FORSECURING LATH TO CHANNEL FURRING 8 Claims.

This application is a continuation-in-part of my co-pending applicationSerial No. 291,803, filed August 25, 1939.

This invention relates to an improved means for erecting lath on channelfurring strips. More particularly, my invention relates to novel formsof clips for securing paper backed wire lath, expanded metal lath andother commercially available lath to channel furring.

Prior to my invention it has been customary to secure expanded metallath, paper backed wire lath and wire-cloth to channel furring by wiretying the lath'to the furring. This procedure requires considerableskill and is time-consuming, thus' makingfthe installation of the lathcostly.

The principal object of my invention is therefore concerned primarilywith an improved means for installing and erecting paper backed wirelath, expanded metal lath, and otherplaster base materials on channelfurring strips.

Another object of the invention is to provide novel forms of resilientclips adapted to secure Various commercial forms of lath, including wirelath, expanded metal lath, paper backed lath and perforated gypsum lath.to channel furring strips.

According to my invention, I` provide resilient clips which can bemanually applied in rapid succession to secure the lath to the channelfurring. the clips being designed so as to be capable of use somewhat inthe fashion of snap-fasteners, one part of the clip being arranged tobear against the outer side of the lath and another part being arrangedto extend into the furring channel and bear against the inner surface ofthe leg thereof against which the lath is placed,

thereby drawing the lath into and holding it in tight engagement withthe outer surface of said leg of the channel.

. Further objects, features and advantages of the` invention will becomeapparent from the following detailed description and from theaccompanying drawings, wherein several embodiments or modifications ofthe invention are set' Fig. 3 is a fragmentary perspective view from theside opposite that shown in Fig. 1, illustrating a partitionconstruction having paper backed wire lath secured by the clips of Fig.1 to the channel furring;

Referring t0 Figs. 1 to 3, the numeral I0 indicates paper backed metallath secured to metal channel furring members II comprising a baseportion l2 and leg portions I3 and I4. The channel furring may beemployed in the construction of the ceiling, as indicated in Fig. 2, andalso in the vertical walls or partitions as illustrated in Figs. 1 and3. These furring members are of well known construction, and may vary insize and be spaced apart at various distances, according to therequirements of building codes. According to my invention, the lath issecured to these channel furring members by means of specially designedclips. One form of such clips is indicated generally by the numeral I5in Figs. 1 to 3.

The clip I5 of Figs. 1 to 3 is more clearly depicted in Figs. 4 and 5.As will be seen from these gures, this form of clip is of generalU-shape and comprises a base portion I 6, an outwardly extendingresilient leg portion I'! and an outwardly extending arcuate andresiliently formed leg portion I9. The leg portion II has a resilient,reentrantly formed portion 20 which is adapted to spring inwardly,allowing the outwardly bent terminal portion 2l thereof to seat or restand bear upon the leg I3 of the channel furring member II when the clipis forced into position over the channel, with the lath positionedbetween the outer face of the leg I3 of the furring and the inner faceof the base portion I6 of the clip.

As illustrated in Fig. 4, it is preferred that the upper or outer endsof the resilient leg portion I'I and the reentrant portion 20 shallextend slightly above or beyond the upper or outer leg member I4 of thefurring, as illustrated. The resiliently formed leg portion I9 of theclip may or may not extend to the same height as the leg portion I'I. Itis obvious that the clip I5 may be so formed that it may be adapted foruse with certain sizes of furring4 so that the number of sizes of theclips may be reduced in order to standardize the clips; that is, a clipI5 may be adapted to be used both with a 3A" and l channel, and anothersize of clip may be adaptedto be used with a 1 and 11/2 channel.

so that there will be marked resiliency between the various leg portionsand-reentrant portions of the clip. The clip may be either galvanized bydipping or electro-plating or have other forms of rustproofing applied`thereto. The clip is so formed that the base .I6 willbe spaced from the.leg E13 of the furring channel l i a distance suicient toaccommodatethe lath therebetween and permit the clip, after it has been snappedinto proper position, as shown in full lines in Fig. 4, to Ldraw andhold tightly the lath against the outer .surface of the leg portion I3.

When the clip is applied, as indicatedcby the dotted linesfin Fig.r4.thereentrant portion 2G is forced outwardly and rides over the edge ofthe leg portion'I3 and then springs back inwardly as its free end passesby the leg portion I3, thus causing the portion i6 to snapintc placeV inene gagement with the inner face of the leg i3. vSince the Vspringaction of the clip is suchthat the reentrant portion 2l) engages andbears against the edge of the other leg I4, and since the portion I5engagesthe lath located between it and the leg I3 of the furringchannel, the resiliently formed leg I9 therefore rmly engages the baseportion I2 of the furring channel and firmly-locks the clip in place onthe furring channel, thereby securing the lath to the channel.Furthermore, as the clip is constructed of flat spring steel wire, theflattened portion of the base vIiand of the'reentrant portion 20 tendsto keep the clip in an upright position. It is obvious therefore, whenthe clip is placed in posi tion over the paper backed wire'lath Il) ofFigs. 1 to ,3 or the expanded metal lath .23 ofv Fig. 4, that the lathis rmly affixed to the furring channel where the clip is applied.

Another form of clip embodying myinvention is shown in .Figs'G to 10.This form of clip is made froma single ,piece of wire which may beveither hard drawn basic Wire or spring steel wire and .of say 13 to 15gauge, depending upon the degree of strength desired in the clip.

This form of clip comprises essentially, a base portion 3I .having'openloops 32 and 33 at the ends thereof, and spaced armsformed integrallywith the loops andextending substantially at a right angle to thegeneral plane of the loops. The arms comprise portions 34, 35 returnbent at 36, 3'I toprovideterminal portions 38, 39.

The wire is preferablyy twisted laterally inwardly adjacent the returnbends 36, 31 so that the terminal portions 433, 39 will converge towardeach other in the direction towards the base portion 3l, the ends 4U, 4Iof the terminal portions being spaced apart a distance substantiallyless than the distance between the bends 3E, 3l.

`In formingthe'loops 32, 33, the wire is twisted,

near the open parts of the loops, so that the portions 42, 43 of theloops are oiset at a slight angle from the plane of the remaining orclosed parts of the loops, and lie on the side of the loops opposite tothat from which the arms 34, extend. The bends 44, 45 at the open endsof the loops thus form a slight bulge which functions to increasematerially the spring action of the clip. This spring action enables theclip to be rapidly applied to a channel furring in the mannerillustrated in Fig. 7. As will be seen from Fig. 7, slight pressing ofthe clip onto the furring in a direction at right angles to the plane ofthe legs of the channel causes the transversely extending arms 34, 35with their converging terminal portions V`38, 3S to spread apart fromtheir normal position and slide over the channel, and when the free endof one of the converging terminal portions has reached the plane of theinner surface of the leg 46 of the channel, the resiliency of the clipwill restore the arms 3, 35 to normal position, thereby causing suchterminal portion to snap into theV channel, with the end 4E offtheportion 39 seated and bearing against the Vinner surface of the leg 45.When the clip is thus properly positioned, the outer end 31 of the arm35 bears against the outer free edge of the opposite leg 41 of thechannel and the lower end-:40 of the other terminal portion 38 bearsagainst the outer surface ofthe base 48 of the channel, therebyrestraining any substantial rocking orV other movementof the clip. l

The length of the wire is such that when bent into the form of clipillustrated and described, the free outer ends 4Q, 4| of the wirevwillbespaced from the portion 3| a distance suilicient to accommodatetherebetween the thickness of the lath 53 to be fastened to the channelplus the thickness of the leg of the channel against which the lath isapplied. An important feature, however, of this form of clip is that byreason of the resiliency imparted yby the outward bending of theportions 42,43 of loops 32, 33, the clip possesses sufficient resiliencyto enable itV to function properly even though the spacing of theendsilll, M of the wire is somewhat less than the sum of the thicknessof the channel and ofthe lath. Under such conditions it is necessaryonly to apply slightly more pressure to, or strike-a light sharp blowat, the portions 42, 43 in order to spring the clip into properposition. Such may Vbe the case, for example, where expanded metal lathis to be secured to the furring and adjacent sheets of the lath overlapone another'as shown in Figs. 6 and '7.

The clip of Fig. 8vmay also be employed for securing the commercialforms Vof perforated gypsum lath to cha-nnel furring. As shown `in Figs.9 and 10, the lath 53a is positioned against the outer face of one ofthe legs of lthe furring in the usual manner. The clip is then insertedthrough any desired number of the perforations l5I of the lath whichoverlie such leg of the The resilient character of the clip shown inFigs. 6 to 10, provides also sufficient play so that while iteffectively holds the lath to the channel furring, there is neverthelesssuflicient freedom of movement so that when plaster has been ap plied tothe lath, the tendency for the plaster layer to crack, as when subjectedto the strain of slight movement of the structure, is greatly minimized.

It will be apparent from the foregoing that by my invention I haveprovided several forms of clips that can be made at very low cost andthat can be rapidly applied in use for securing various commercialvarieties of plastering base material, such as expanded metal lath,paper backed wire lath and gypsum lath to channel furring strips.Moreover, the clips are of such form and design as to be capable ofbeing rapidly applied by unskilled workmen and without requiring the useof any special tools in order properly to position the clips in theircorrect functional relationship with the channel furring.
